Qualitative spatial reasoning based on fusion combinative table

Qualitative spatial reasoning is representation, analysis and process for qualitative spatial relations. Based on topological relation model HBM and direction relation model D-14, we give the combinative table and reasoning method. In allusion to the result of combinative table reasoning is non-unique, the conception of fusion combinative table and the algorithm for fusion combinative table reasoning are presented. It is eftctive to reduce the non-unique of combinative table reasoning result, and to make the combinative table reasoning more flexible and practicality.
